Подтверждаю баг с английского форума viewtopic.php?f=39&t=10149
Победил - наплевав на креатив, и сделав моторную лодочку из blueprints. Если же делал монструозные плоты с водяными колесами - фриз.

можно сейв и инструкцию как повторить? очень уж баг неприятный, надо-бы поправить

поправили. фикс зальем на стим ночью.
к сожалению в сейвах ошибка останется. т.е. нужно либо играть с начала, либо это место пройти загрузив лодку из чертежа.

на всякий случай приложу кусок лога

да, это оно.
стройте лодку из чертежа, играйте дальше, все будет в порядке. Баг локальный, на дальнейшую игру не влияет
